WINIJOlfV-LIFTING DEVICE.

Application filed March 29, 11917.

dow may be raised or lowered to any de-V sired position, and automatically locked in such position. y l

Further objects, and objects relating to' economies of manufacture and details ot construction, will definitely appear in the detailed description to follow.

I accomplish theobjectsoi lmy invention by the devices and means described in the following `specification and my invention is clearly denedand pointed out in the appended claims.

A structure constituting a preferred ernbodiment ofiny invention is illustrated in the accompanying drawing, forming a part ci this specification, in which:

Figure I is a transverse 4sectional view of a vehicle door showing apreferred forni oi' my invention attached thereto;

Figure II is a fragmentaryelevational view of my window operating device attached to the sash;

Figure III is an enlarged sectional view taken substantially on line 3 3 ot Figure II showing the automatic lock and drivin means for 'the driving sprocket; i

F igure` IV is an enlarged sectional yview taken on line 4 4 of Figure II, showing 'the driven sprocket and automatic take-up for the driving chain;

Figure V is a detail sectional viewtaken on line 5 5 of Figure II'. l

Figure VIl is la fragmentary elevational view of the driven sprocket taken on line 6 6 oit' Figure IV;`

Figure VII is a perspective view of the handle grips;

Figure VIII is a detail `sectional view taken on line 8 8k ofFigure -IIII showing the handle rips and their mounting; and

FigureIg is an elevational view of the Serial No. 158,194.

driving sprocket taken on `line 9 9 of Figure III. i

In the drawings, similar reference characters referto similar parts throughout the several views andthe sectional views are taken looking in the direction olithe little arrows at thek ends ot the section lines.

Considering the numbered parts of the drawings; 1l represents a vehicle door or any standard' construction, and 2 the window sill integral therewith. The glass panel. 3 is slidably mounted in ways 4 at the sides ol? the door 1, the glass panel being adapted to be raised or lowered, and is so operated by my improved'ioperating device, the description of which is as follows:

My improved mechanism is mounted on a spacing bar 5, (Figs. II and III), which Ais secured to the door by means of the cross plates 6. The upper end ot the spacing bar 5 `has an offset portion .7 and on the opposite side of the offset portion 7 is an otl'set portion 8, welded or otherwise secured to the said spacing bar, these two offset portions 'i' and 8 forming a fork to support the enlarged end portion 18 at its inner end, and

is secured at its outer end by the cotter pin 20. Mounted onk the post'l? isa spring 19, one end of which abuts against the enlarged end 18 of the post 17, andthe other end against the oiiset portion 12" of the hub 12, thus drawing the driving sprocket and hub into locked position. rIhe driving sprocket 9 has a series of holes 21 adapted to be engaged by the stop pin 22, which is mounted on the offset portion 7 ol the spacing bar 5. Itwill be seen that as the parts are in their normal` position and the stop pin l22 engages one of the holes 21, the driving sprocket 9 is held in locked position against rotation and the sash 3 will stay in the desired position where set.

At the lower end of the sash 3 is mounted normaily locking said sprocket; spring means normally retaining said sprocket in locked position; and a device for first moving said sprocket axially against the tension of said spring means to release the sprocket and then rotating the sprocket to operate the chain.

G. ln a Window lifting device, the combination `With a movable member and a driving chain tor actuating the same; oit a sprocket for operating said chain and provided with openings; a fined stud cooperating with the openings in said sprocket to normally lock the same; spring means normally retaining` said sprocket in locked position; and a. device for rst moving said. sprocket axially against the tension of said spring means to release the sprocket and then rotating the sprocket to operate the chain.

7. In a Window lifting device, the combination with a movable member and a driving chain tor actua-ting the same 5 of a sprocket for operating said chain; means normally locking said sprocket; a handle given a lateral movement to move. the sprocket axially to release the same and given a rotating movement to rotate the sprocket; and spring means for moving the handle and sprocket axially when the handle is released to move the sprocket into locking position.

8. In a Window lifting device, the combination with a movable Window and a driving chain ior actuating the same; of a sprocket 'for operating said chain and provided with openings; a fixed stud co-operating with the openings in said sprocket to normally lock the latter; a handle given a lateral movement to move the sprocket axially to release the same and `given a rotating movement to rotate the sprocket; and spring` means for moving said handle. and sprocket axially when the handle is released to move the sprocket into locking position.

kmember slidably and rotatably mounted in f said bearings, a sprocket secured upon said actuating member, means adapted to normally lock the sprocket against rotation and adapted to release the same upon longitudinal movement ot said actuating member, and means operatively connecting the sprocket with the Window to eilect the raising and lowering of the same upon rotation ott said sprocket.

l0. ln a. ivindoiv lifting device, the combination of a niovable Window7 apair of spaced rotatable members one of which is mounted for axial movement locking means releasably engaging said axially movable member to permit rotation of the same7 a belt connecting said rotatable members. means coimectinp` said belt with said window to effect movement of. the same in opposite directions, and means .tor rotating said axially movable member.

ll. In a Window liftingdevice, the coinbination of a movable Window, a pair of sprockets7 a support for one oit the sprocketsj a fork in which the other sprocket is mounted, a forked frame member in which said fork is slidably and yieldably mounted, a chain connecting said sprockets, means connecting the chain with said movable Window and means for actuating one of said sprockets.

l2. In Window lifting device, the combination of a movable Window, a pair of forked members one'of which is yieldably mounted npon the other, a sprocket carried by each oit said members7 a chain connecting said sprockets.4 means connecting the chain With said Window and means adapted to ro tate one of said sprockets.

In Witn ess vvhereot I affix my signature.
